Abstract
Early detection of plant diseases can substantially reduce pesticide use, offering significant environmental and economic benefits. Agriculture consumes over 18,000 tons of pesticides annually in the EU alone, with 40–60% applied unnecessarily before disease symptoms manifest. Here, we present surface functionalization of CMOS capacitive sensor arrays using SonoPlot direct-writing of porous materials for low-power electronic nose (E-nose) applications. Utilizing advanced SonoPlot printing for precise material deposition, we functionalize sensor surfaces to optimize VOC adsorption, enabling real-time detection through capacitance changes. Our results show that a wide range of polymers and porous materials, including UV-curable inks, carbon nanoparticle-based polymers, metal-organic frameworks (MOFs) such as CAU-10 and CAU-23, and Prussian blue analogs (PBAs) such as CuPBA, exhibit high selectivity toward VOCs, including 1-nonanol, 2-nonanol, α-terpinene, tetradecane, 1-butanol, 2-butanol, 1-propanol, 2-propanol, ethanol, toluene, α-pinene, and water vapor. This research highlights the potential of SonoPlot printing technology to enable next-generation, high-performance, and cost-effective printable E-nose VOC sensors, offering significant promise for widespread environmental sensing applications.
